ABSTRACT

Like many Republican presidential candidates before him, Donald J. Trump campaigned on a pro-business, anti-regulation platform, and since his election in November 2016, he has directed his administration to move forward with deregulation in many arenas, including consumer financial protections, environmental controls, and workplace safety among others. Past efforts to roll back regulations governing certain industries, such as the savings and loan and the mortgage industries, have had harmful consequences for the general public or for specific interest groups. In this study, we review what the Trump administration has accomplished with regard to deregulation to date. Then, based on past deregulatory fiascos, we theorize the harmful collateral consequences that may result from this most recent swing of the regulatory-deregulatory pendulum.  相似文献

Fatal fall from a height initiated with a swinging motion on the sagittal plane of the victim's body is examined. Method of analytical mechanics is adopted to establish the functional relations between the swinging angle of the body and the force needed to sustain the body until release, and the amount of the horizontal displacement that would occur after release. The analysis is applied to support an expert opinion presented in a criminal court in which two accused were convicted of murder for dropping a female victim from a bridge. The results indicate that it is unlikely for the body to locate as recorded by the police investigation report in the case. This study demonstrates that a straightforward mechanical analysis can be utilized to examine uncommon falling scenarios.  相似文献

Abstract

Although the Syrian conflict continues, local and global stakeholders have already begun to consider the return of the six million refugees, especially as neither the option of local integration in the countries of first asylum nor that of resettlement to third countries is seen as a realistic possibility. Elaborating on the return debates in Turkey, Lebanon and Jordan, we relate the politicisation of this question to the growing acceptance of the option of voluntary and involuntary repatriation in the international refugee regime as well as to policies and public opinion. We argue, based on empirical fieldwork, that any debate about the return of Syrian refugees is problematic, since the conditions of safety, voluntariness and sustainability are not fulfilled. Further, returns should not be left entirely to the individual hosting states and actors in the region but should be carried out in collaboration with representative authorities in Syria and the mediation of international organisations upon full resolution of conflict.  相似文献

This paper describes several dimensions of the cost of the U.S. response to the threat of terrorism. Following an evaluation of the nature and magnitude of the threat of terrorism against the United States, the paper describes the restrictions on our civil liberties, the fiscal and other costs of the major homeland security measures, the fiscal cost of programs that make no contribution to the defense against terrorism but are rationalized on that ground, and the effects on our language and the potential for civil discourse of an extended defense against terrorism.  相似文献

In many states, legal representation for parents of dependent children is inadequate and can be a source of delays in securing permanency for children and unnecessarily protracted court proceedings. Often, such parents also face barriers to accessing services and independent evaluators. These issues are being addressed in the state of Washington through two approaches. The first is a successful enhanced legal representation program that has substantially improved case outcomes. The second is a statewide committee using innovative means to examine systemic responses to the challenges of the Adoption and Safe Families Act.  相似文献

This paper uses historical content analysis to examine the implementation ofthe Racketeer Influenced Corrupt Organizations Act (RICO). It is argued thatthe historical events leading to the definition of organized crime as an alienconspiracy still affect RICO's use some 30 years after its passage. This paper applies state-centered theory to the theoretical frameworks of sociology of knowledge and innovation diffusion. This approach is used to relate the current implementation and controversy of RICO to the alien conspiracy view. Thought of in this context, legal implementation is the result of a knowledge creation and diffusion process. This paper demonstrates how one knowledge diffusionprocess (the acceptance of organized crime as a national conspiracy in 1970) leads to a new knowledge diffusion process (the use of RICO).  相似文献

Data on bone tissue fractography are summarized and systematized. Possibilities of a microscopic fractography method in analysis of skeletal bone fractures in order to determine conditions of traumatic exposure were shown. Destruction of bone tissue is considered from the point of view of fragile and tough destruction using as a model solid body with crack at the top of which deformations of detachment, lateral and longitudinal shifts are acting. Morphologic features for different types of destruction were singled out. Use of these features may help to determine character and type of deformation at concrete areas of fracture during all destruction process.  相似文献
